In a small sauce pot over medium-high heat, bring sugar and water to a boil, then turn down to low and simmer until the sugar is dissolved. This takes about 3-5 minutes. This creates a classic simple syrup that you can use in almost any sorbet recipe.
Remove simple syrup from heat and allow to cool.
Pour orange juice into a large bowl.
Once the simple syrup is cool, add to the bowl of orange juice and mix with a whisk gently until the sugar and orange juice are well blended.
Turn on your ice cream maker, pour the mixture through the top opening, and allow to do its magic according to manufacturer instructions. My ice cream maker turned the mixture into a lovely orange juice sorbet in 30 minutes.
Notes
Enjoy immediately, or store in an airtight container in the freezer for up to three weeks (if it will last that long without being gobbled up!).
